Valentine MkIX tank at Kubinka, March 1943

"Firing in place and on the move
Gunnery trials were performed at ranges of 500 and 1000 yards (457 and 914 meters) at targets 4x6 meters in size. Each group had 10 shots. There was no time limit on firing. Aiming was done using the telescopic sight. The weather was clear, visibility was 2000-2500 meters.
Results are given in table #4.
|Range (yards)||# of shots||# of hits||Mean vertical deviation, cm||Mean horizontal deviation, cm|
|Moving at 10 kph||400-500||10||10||95||75|
Comparing the data in table #4, one can see that:
- Mean vertical deviation is higher than mean horizontal deviation in all cases. This is explained by a wobble in the elevation mechanism and a turning of the flywheel when the firing lever placed on the flywheel is pulled.
- Mean deviation when firing from the move is 11 times greater than when shooting from a standstill from the same distance. This happens due to the stiffness of the suspension and the insufficient traction of the tracks on the ground, which leads to the tank slipping and the turret wobbling, which makes it difficult to aim the gun.
Maximum rate of fire in place and on the move
The maximum aimed rate of fire was measured at a range of 700-1000 yards (640-914 meters). Aiming was performed using the telescopic sight using the mechanical aiming mechanisms. Each group consisted of 5 shots. The weather was clear, visibility was 2000-2500 meters.
Results of trials and hits on target are given in table #5.
|Hit||Close miss||Overshot||Undershot||Deviation in direction|
|In place. Range= 1000 yards||5||3||2||-||-||-||30 sec||10||60%|
|Moving at 9-10 kph, at 0 degrees, at one target||5||2||2||-||1||-||1 min. 51 sec.||2.7||40%|
|Ditto, at two targets||5||1||1||1||2||-||1 min. 47 sec.||2.8||20%|
|Ditto, at three targets||5||-||-||2||3||-||2 min. 4 sec.||2.5||0%|
|Moving at 15 kph, at 0 degrees, at one target||5||-||-||3||2||-||2 min. 24 sec.||2.0||0%|
- The English Valentine IX tank differs little from the Valentine III tank. The main difference is the use of a 6-pdr gun in the Valentine IX, a lack of coaxial machinegun, and thinner side armour.
- The speed and maneuverability of the two tanks are nearly identical, with the exception of range, which increased in the Valentine IX by 90% due to external gas tanks.
- The 57 mm gun on the Valentine IX has an unreliable recoil brake.
- Unsatisfactory results when firing from the move, 20% hits, are achieved due to significant wobble in the aiming mechanisms.
- A lack of HE grenade for the 57 mm gun limits the usefulness of the gun.
- A lack of coaxial machinegun limits the usefulness of the tank when fighting enemy infantry.
- Valentine IX and Valentine III tanks are equivalent technically.
- The armament of the tank makes it only useful against enemy tanks.
- The lack of an HE grenade and a coaxial machinegun makes the tank unable to fight enemy infantry and fortifications.
- The reliability of the 57 mm gun needs to be tested on a series of samples."
